Engineering Contradiction Analysis
1Device complexity
If 1TX/1RX communication format is used, then device complexity is reduced, but data throughput decreases and collisions occur
Solution Approach 1:
The patent implements dynamic communication modes that allow the system to switch between 1TX/1RX format and full-duplex format based on current operational requirements. The controller dynamically adjusts the communication format to optimize data throughput while managing collisions, enabling high-speed data transmission when needed while maintaining simplified operation during normal conditions.
2Device complexity
If 1TX/1RX communication format is used, then device complexity is reduced, but response time increases
Solution Approach 1:
The system dynamically switches between communication formats based on latency requirements. For latency-sensitive applications like gaming, the controller activates full-duplex mode to enable simultaneous transmission and reception, significantly reducing response time while maintaining manageable device complexity through automated mode selection.
3Reliability
If encryption is added to wireless communication, then security is improved, but power consumption increases
Solution Approach 1:
The patent implements variable encryption parameters that adapt to current security requirements and power availability. The system can adjust encryption strength, key update frequency, and authentication overhead based on operational context, providing strong security when needed while reducing power consumption during battery-operated or low-power modes.
4Reliability
If encryption is added to wireless communication, then security is improved, but data throughput decreases
Solution Approach 1:
The system dynamically adjusts encryption parameters to optimize the balance between security and throughput. By varying key lengths, authentication frequencies, and encryption algorithms based on data sensitivity and bandwidth requirements, the system maintains strong security for critical data while allowing higher throughput for less sensitive communications.
Data Source
AI summary
A wireless peripheral device operatively coupled to a wireless dongle of an information handling system includes a microcontroller to receive a polling packet from the operatively coupled wireless dongle, via a wireless peripheral device radio, identifying a selected number of encrypted data packets for a data packet frame. The microcontroller executes code instructions of a wireless input/output protocol authenticated encryption agent with bi-lateral linear-feedback shift register (LFSR) input stream to generate an initial key or a later dynamic key. With the initial key or dynamic key, the encryption system uses a shifting state machine output from each of a first and second LFSR in an encryption algorithm to generate a data packet encryption output value. The data packet is encrypted via an XOR operator with the data packet encryption output value, and each generated data packet encryption output value is subsequently the dynamic key for encryption of subsequent data packets.
